What should you know about squamous cell skin cancer spread to lymph nodes?

Lymph nodes are small immune-system structures that drain fluid from nearby tissues. A lump in the neck, under the jaw or near the ear can have many causes, so examination and tissue testing are needed before deciding that cancer is present. Doctors may use imaging, needle sampling or removal of a node, alongside review of the original skin tumour.

The findings help the team assess whether disease is limited to regional nodes or has travelled farther. Treatment may involve tumour removal surgery, treatment of affected nodes, radiotherapy or immunotherapy in selected advanced cases. The plan depends on the number and location of involved nodes, the skin tumour’s features and your general health.

Tell your clinician about a new or growing lump, tenderness, skin changes or swelling near the original tumour. Bring biopsy and scan results to the consultation if available. Ask whether the lymph node needs sampling and whether a head-and-neck or skin cancer team should coordinate the plan.

Contact the care team promptly for a rapidly enlarging node, increasing pain, new weakness, difficulty swallowing, persistent hoarseness or swelling of an arm or face. Seek emergency help for breathing difficulty, inability to swallow fluids, severe bleeding or sudden neurological symptoms.

Has the node been confirmed as cancer? Are other nodes or organs involved? What is the goal of surgery, radiotherapy or immunotherapy? Will treatment affect swallowing, movement or appearance? How will follow-up check the skin and lymph-node areas?
